🦬: I protect, I attack, and most importantly, we fight back.

Muskoxen stick close together as they move and feed across the tundra. And when predators threaten the herd, they cluster together to form a protective wall around their calves. 🛡️

But don’t let their wholesome herd behavior fool you. During mating season, you’ll often see males battling each other to assert dominance and impress potential mates. 👊

You'd think dinosaurs would be old enough to brush their own teeth. 🙄

While "dino dentist" may sound like a nightmare job (unless you're a paleontologist), somebody's gotta take care of the fossils. 🦴

This photo of our Daspleotsaurus from 1976 shows how our team keeps up with the dinos through dusting and vacuuming, keeping our specimens looking their best. 🧼

Chicago had Chance the Snapper. Wyoming had... this guy. 🐊

Meet Tsoabichi Greenriverensis, a caiman relative that lived 52 million years ago in what is now Wyoming. 🌎

Just like the folks who first spotted Chance the Snapper, you might be wondering what a crocodilian was doing making itself at home in a place known for some seriously frosty weather. ❄️

But 52 million years ago, Wyoming looked very different. Back in the Eocene, the region was warm and tropical—nothing like the harsh winters that we know today. ☀️

Finding fossils like Tsoabichi gives scientists clues about how dramatically the climate and Earth have changed over millions of years. ⏰

This diorama is one of the few places on Earth where you can see these bears. 🐻

Mexican grizzlies once lived in shrubby foothills at the base of mountains in northwestern Mexico. When Field Museum scientists collected these specimens in 1900, they were common. 🏔

But by the 1960s, hunters and ranchers had driven the bears out of the foothills and into mountain pine forests. Continued hunting and habitat destruction eventually drove the bears to extinction. 🪵

More than a century after it was made, this diorama teaches us about animals we'll likely never see again— and serves as a reminder of the importance of conservation. 🌎

⚡️ Pokémon Fossil Museum: Aerodactyl and Pterosaurs

Aerodactyl shares key features with pterosaurs from our world.

🔵 Aerodactyl: This ferocious prehistoric Pokémon is thought to have gone extinct when a large meteorite struck. Its wings, many sharp teeth, and pointed tail make it a fierce Pokémon, often aiming for its enemy’s throat in battle.

🔴 Pterosaurs: These real-world flying reptiles (which aren’t actually dinosaurs) lived until their extinction 66 million years ago. This family's key features include a thick lower jaw, a long, pointed tail, and prominent skull crests that can be found on many pterosaurs.

Welcome to the Jungle, Slash's groundsnake! 🐍

Slash, aka Saul Hudson, is probably best known as the guitarist from Guns N' Roses, but there's more to Slash than just his music! 🎸⚡️

He's also a lifelong reptile lover and an avid supporter of zoos and museums. And now, he's the namesake of the newly discovered Lielaphis slashi: Slash's groundsnake! 🏛️

This 28-inch-long reddish-brown snake comes from the forests of New Guinea, an island located north of Australia that is divided between the countries of Indonesia and Papua New Guinea. 🌏

Snakes in this genus often have large teeth in the back of their mouths, which New Guinea groundsnakes may use to grab onto and eat small, slippery-scaled lizards and the eggs of other reptiles. 🥚

While Guns N' Roses has been called "the most dangerous band in the world," L. slashi does not produce any venom that could seriously harm a person. 🥁

While Slash’s groundsnake doesn’t pose a threat to humans, human activity could spell disaster for this snake and its fellow forest-dwelling creatures' habitat. 🌳

Recognizing and describing new species like this one is an important step for us to better understand how ecosystems work and how everything fits into the environment. In order to conserve and protect living things, we first have to learn about them. 🔎

"That's one big dinosaur!" ❌

While they are often lumped together, pterosaurs aren't actually dinosaurs at all! 🦖

Sure, they may have lived alongside one another, but pterosaurs made up their own distinct group of flying reptiles. 🪽

Among this group was the Quetzalcoatlus, one of the largest animals to ever fly. This massive beast stood as tall as a giraffe and soared through the skies with a wingspan of 30-35 feet. That's about the same size as a small airplane! ✈️

A really, REALLY big snake 🐍

If you thought the 20-plus-foot anaconda was big, get ready to meet the GIANT Titanoboa. 📈

When Titanoboa slithered through South America 58-60 million years ago, it measured in at 40+ feet long and weighed more than a ton—twice the length and four times the weight of its modern relatives. 😳

Scientists can estimate the super-sized snake's size by comparing its vertebrae to today's snakes. If Titanoboa had the same proportion as a green anaconda, its body could have been as much as 30 INCHES thick. 😱

Titanaboa's massive potential may have been due to its hot climate: climbing temperatures during the early Paleocene meant fewer mammalian predators, a lack of competition, and room for the snake to keep growing. 🐅

Come face-to-face with our life-sized Titanoboa in our new special exhibition, After the Age of Dinosaurs ➡️ 🔗 fieldmuseum.io/aftertheageofdinos

Getting ready for back to school like: 🐟🐠🐡

This school of funky looking fish are from the ichthyology volumes of the Naturalist's Library, a popular natural history series published in the mid 1800s. 📚

Before photo and video could easily capture and share the natural world, detailed scientific illustrations like these helped people learn about species from all across the globe, turning scientific knowledge into something people could see and share. 💙

⚡️Pokémon Fossil Museum: Archen, Archeops & Archaeopteryx

Unlike other Pokémon with beaks and feathery tails, Archen and Archeops have sharp teeth and solid tails.


🔵 Archen: This Pokémon can’t fly and moves about by hopping from branch to branch.


🔵 Archeops: For Archeops, flying isn’t as easy as it looks; this Pokémon first needs to run nearly 25mph, building up speed over about 2.5 miles before it can finally take off.


🔴 Archaeopteryx: This real-world fossil is the oldest known fossilized bird and the animal that revealed to scientists that birds are dinosaurs.

Beach day + fossil hunting? Sounds like a pretty good day, if you ask us. 🪨🌞

These weird rocks are Petoskey stones: 385-million-year-old pieces of colonial rugose coral (Hexagonaria percarinata) that can be found along the Lake Michigan shoreline.

They're made up of the hexagonal skeleton structures of individual coral polyps, or corallites, and have been polished by tumbling through the waves.

While some fit in the palm of your hand, these coral colonies could get MASSIVE. The largest Petoskey stones weigh in at over 1,000 pounds and measure nearly four feet across.

Never take a rock for granite.* Shore up your Chicago fossil knowledge with our Beachgoers Guide to Lake Michigan Rocks and Fossils ➡️ fieldmuseum.io/beachgoersguide

*Unless you've verified that it IS, in fact, granite. 🪨✅
